When interviewing for a front-end developer role, you will be asked many different technical questions about a wide variety of technologies used when designing websites. While it is impossible to know about every one, you should be familiar with the major topics and discuss them in some detail. If, for some reason, you aren't familiar with the topic raised by the interviewer, quickly admit this and then describe how you would go about locating the information.

"CORS is an acronym which stands for Cross-Origin Resource Sharing. You can use CORS to make requests from one website to another one. CORS addresses a browser not being allowed to load requests to other domains when scripts generate those requests. This is prevented for security reasons. By supplying a header that will define which domains can make appropriate requests, CORS is a good work-around for this limitation."
